Sorry, Pokemon Go addicts, playing the video game doesn't count as a real workout

Harvard University researchers have some bad news for Pokemon Go enthusiasts: The time you spend hunting digital monsters doesn't qualify as a workout. After analyzing the movements of actual players, the researchers calculated that Pokemon Go encouraged people to take an average of 955 extra steps per day in the first week after downloading the game. Assuming that each step covered 31.5 inches and that players walked at a pace of 2.5 miles per hour, the game prompted people to walk for 11 extra minutes each day. The World Health Organization recommends that adults get at least 150 minutes of aerobic physical activity each week. If you spread that equally throughout the week, you'll need to get 21.4 minutes of exercise each day -- twice as much as Pokemon Go provides.
